Code signing with PFX certificate

Hello,

I created a certificate to sign a NET WinForm control. The certificate was
locally generate on a Win2K server, I also tried using a Win2003 server.

When I assign the Assembly keyfile with the certificate file and compile the
C# control I get a "bad version provider" error.
As a additional information I have used the Win2K server to sign macros in
the past with no problems at all. This seems to be related to NET framework
1.1.

I looked up on msdn and couldn't find information about this error. I will
appreciate help to resolve this.

thank you
